I have hunted coyotes of and on for some time with my deer rifles but now that I am addicted a want to purchase a varmint rifle. I am having a hard time deciding between an older remington 700 heavy barrel .223 which is in mint condition and a tack-driver or a brand new weatherby vangard in 22-250. I am leaning more towards the .223 due to cheaper ammo and surplus supply's. Any Imput on If I should go up to the 22-250 or stick with the .223 would be much appreciated!
